Typically the standby generator can only power a small part of the
building load. Non-essential circuits are shed as the generator starts
up. With the generator running it may not be desirable to go back to
the external supply automatically if it does become healthy, it might
fail a minute later. Thus the building may run with only essential
circuits for some time until people are happy with the external supply.


In these days where everything is computer controlled and your
servers are probably the most important business-critical device (see
the cases of various supermarkets which have to close for the day
because their accounting software is on the frizz), keeping them
working also needs air-conditioning. So when things like this happen
you'll be sitting in the dark, bathed only by the strangle glow of
computer screens, unable to do many jobs that require manual dexterity
- like going for a pee in a totally dark toilet - but in a nice,
comfortably cooled environment.

Personally I have no problem going for a pee in a dark toilet - neither
do totally blind people. However it is recommended that men sit down on
this kind of occasion.
